Abstract

Objectives: To investigate the effects of various arm positions on median nerve conduction studies (NCSs).

Methods: This prospective cohort study, conducted at Adana City Training and Research Hospital between January and July 2023, included 20 healthy participants. Median NCSs were performed on the participants in three different standing positions with the elbow as the stimulation point: 1) with the arm adducted (P1), 2) with the arm anteflexed (P2), and 3) with the arm raised upwards (P3). We obtained median nerve compound muscle action potential (CMAP) latency, duration, peak-to-peak (PP) amplitude, onset-to-negative peak (OP) amplitude, negative area/duration. Three CMAPs were obtained in each position, and the mean and minimum/maximum values at each position were analyzed.

Results: The mean age (minimum-maximum) of the participants (11 male, 9 female) was 28.5±6.5 (20-42) years. Median nerve CMAP means (median) of latency/negative duration in the P1, P2, and P3 positions were 6.82±0.59 (6.83)/5.50±0.76 (5.39) ms, 6.99±0.56 (7.02)/5.72±0.73 (5.73) ms, and 7.03±0.58 (7.12)/5.79±0.80 (5.83) ms. Median nerve CMAP mean/minimum latency and negative duration were lowest in the P1 position (p<0.05). The mean median nerve CMAP OP amplitude was highest in P3 than P1 or P2 (p=0.042 and p=0.048).

Conclusion: Median NCS results differed based on the position of the arm.

不同手臂姿势下的正中神经传导研究结果。

目的：研究各种手臂姿势对正中神经传导研究（NCS）的影响：研究各种手臂姿势对正中神经传导研究（NCS）的影响：这项前瞻性队列研究于 2023 年 1 月至 7 月在阿达纳市培训与研究医院进行，共纳入 20 名健康参与者。以肘部为刺激点，在三种不同的站立姿势下对参与者进行了正中神经传导检查：1）手臂内收（P1）；2）手臂前屈（P2）；3）手臂上举（P3）。我们获得了正中神经复合肌肉动作电位（CMAP）的潜伏期、持续时间、峰-峰（PP）振幅、起始-负峰（OP）振幅、负面积/持续时间。每个体位获得三个 CMAP，分析每个体位的平均值和最小/最大值：参与者（11 名男性，9 名女性）的平均年龄（最小值-最大值）为 28.5±6.5 (20-42)岁。正中神经 CMAP 在 P1、P2 和 P3 位置的潜伏期/负持续时间的平均值（中位数）分别为 6.82±0.59 (6.83)/5.50±0.76 (5.39) ms、6.99±0.56 (7.02)/5.72±0.73 (5.73) ms 和 7.03±0.58 (7.12)/5.79±0.80 (5.83) ms。正中神经 CMAP 平均/最小潜伏期和负持续时间在 P1 位置最低（pp=0.042 和 p=0.048）：结论：正中神经 NCS 结果因手臂位置而异。

期刊介绍： Neurosciences is an open access, peer-reviewed, quarterly publication. Authors are invited to submit for publication articles reporting original work related to the nervous system, e.g., neurology, neurophysiology, neuroradiology, neurosurgery, neurorehabilitation, neurooncology, neuropsychiatry, and neurogenetics, etc. Basic research withclear clinical implications will also be considered. Review articles of current interest and high standard are welcomed for consideration. Prospective workshould not be backdated. There are also sections for Case Reports, Brief Communication, Correspondence, and medical news items. To promote continuous education, training, and learning, we include Clinical Images and MCQ’s. Highlights of international and regional meetings of interest, and specialized supplements will also be considered. All submissions must conform to the Uniform Requirements.
